tween saine and the rubber, whereby the rubber and the stifEening-strip form a practically-integral mass, thus avoiding all relative chaling and cutting.

By my means of securing the tire on the rim the compression in the tire due to the manner of fastening same as distinguished from compression of the tread to resist cutting (effected by vulcanizing same on a smaller diameter than that of the wheel upon which said tire is intended to be mounted) is limited entirely to the lower base portion, thus leaving a greater sectional area of the tread portion resilient and elastic than in the Wirefastened tires at present generally used. The hollow core in said tire remaining after the stiiening-strip has been drawn tight also gives a cushion effect to the tire and adds to its resiliency, thus making it softer and en abling it to withstand lateral strains and mount obstructions presented at an acute angle to the direction of motion. By thus making the tire softer and more elastic the vibration occasioned in traveling over a rough road is absorbed by the tire to a far greater extent than with the tires at present in use, thus prolonging the life of the vehicle and enhancing the comfort of the occupants. By arching the stilening-strip to surround the groove or channel C the tread is prevented from compressing radially to an undue eX- tent, while at the same time such radial pressure is transmitted laterally toward the ilanges of the tire, which is also desirable, as materially increasing the resiliency. The insertion of the metallic stilening-strip is also advantageous, inasmuch as the rubber adjacent same is vulcanized to a greater degree than the balance of the tire, thus making the base of said tire stiffer than the tread. Said groove or channel C can be variously shaped in its widest portion, its outermost side or bottom being either flat or rounded. A heavy wire may also be substituted for the band F, it being essential only that such wire should be of greater diameter than the width of the mouth of said groove or channel C. The stilieening-strip G may also consist of material other than wire-cloth, as shown in Fig. 6, duck or similar material being substituted therefor and inserted in any suitable manner, themanner of insertion being dependent upon the material employed.

In Fig. 7 I have illustrated a tire provided with two dovetail grooves or channels C, which.
